Crate bitcoin_io 

Rust Bitcoin I/O Library

The std::io module is not exposed in no-std Rust so building no-std applications which require reading and writing objects via standard traits is not generally possible. Thus, this library exists to export a minimal version of std::io’s traits which we use in rust-bitcoin so that we can support no-std applications.

These traits are not one-for-one drop-ins, but are as close as possible while still implementing std::io’s traits without unnecessary complexity.

For examples of how to use and implement the types and traits in this crate see io.rs in the github.com/rust-bitcoin/rust-bitcoin/bitcoin/examples/ directory.

Modules

error

Error types for the io crate.

Structs

Cursor

Wraps an in memory buffer providing position functionality for read and write.

FromStd

A bridging wrapper providing the I/O traits for types that already implement std I/O traits.

Sink

A sink to which all writes succeed.

Take

Reader adapter which limits the bytes read from an underlying reader.

ToStd

A bridging wrapper providing the std traits for types that already implement our traits.

Traits

BufRead

A trait describing an input stream that uses an internal buffer when reading.

Read

A generic trait describing an input stream.

Write

A generic trait describing an output stream.

Functions

decode_from_read

Decodes an object from a buffered reader.

decode_from_read_unbuffered

Decodes an object from an unbuffered reader using a fixed-size buffer.

decode_from_read_unbuffered_with

Decodes an object from an unbuffered reader using a custom-sized buffer.

decode_from_read_with

Decodes an object from a buffered reader using a Decoder type.

drain_to_writer

Drains the output of an Encoder to an I/O writer.

encode_to_writer

from_std

Wraps a std I/O type to implement the traits from this crate.

from_std_mut

Wraps a mutable reference to std I/O type to implement the traits from this crate.
